Could use a bit better level design (I can just double jump over some of the larger gaps at some points and some turns and colors and jumps are just hard to see or notice making it fairly hard to beat) and just adding a bit better looking world outside of the endless abyss on either side and odd colored platforms floating in the air. Also adding some more game features such as more things to pick up as you go and some power ups and things such as that. Also adding maybe a difficulty setting where its much faster paced or more obstacles in the level or something of that sort otherwise interesting game and shows allot of potential.
Great bullet gell game excluding some of the bugs and the lack of large upgrades its tons of fun and I can't wait for a sequel or some updates for the game.
